Cross-Platform Marketplace App with Node

@KESHAVINFOTECH

Hi There, 1.I need a robust buy-and-sell marketplace built as two fully-native a... ==> We understand you need two separate native apps for iOS and Android for your marketplace. We have great experience building these kinds of apps. In one of our past projects, we also included a cool feature where sellers could join live, themed selling events inside the app to show their products to many buyers at once. We also got the idea for the backend and admin panel. We will build a strong API using Node.js and MongoDB with proper security like JWT tokens and user roles. The web admin panel to manage listings, users, and handle problems is also very clear. Handling the main features like real-time chat, secure payments with Stripe, and push notifications is something we are very comfortable with. ## Queries : 1. When a dispute arises, does the buyer initiate it directly from their order details screen, or is there a separate support/contact flow to start the process? ## Initial Project Structure : - Onboarding & Auth - Home Feed - Product Details - Advanced Search - Create Listing - In-app Chat - User Profile - Checkout Flow - Order Management - Admin Panel We use advanced AI tools (Cursor, Claude, ChatGPT) to speed up coding and reduce manual work hours. We pass these time-savings to you, providing a high-quality app at a very competitive price. Waiting for your reply. :-) Regards, Ghanu & Samir. KESHAV INFOTECH

NATIVE MARKETPLACE: ESCROW PAYMENTS ARE THE CRITICAL PATH Stripe escrow for a buy sell marketplace isn't standard Stripe Checkout it requires Stripe Connect with held funds, conditional release on order completion, and refund logic that handles disputes before payout. Most developers wire basic Stripe payments and retrofit escrow later. That's a re architecture mid-project on a 7 15 day timeline. Our build: Swift/SwiftUI (iOS) + Kotlin (Android) native apps, product catalogue CRUD, image uploads, advanced search and filtering, APNs/FCM push notifications Node.js + MongoDB REST API, JWT auth, RBAC for buyer/seller/admin roles, WebSocket real time chat, Stripe Connect escrow with refund and payout logic React admin panel listing moderation, user verification, dispute management 12+ years in house. iOS, Android, backend, and payment logic owned by one team no Stripe specialist brought in after the API is already built. Generic marketplace builds treat payments as a feature. Escrow logic touches the order state machine, chat triggers, and admin dispute flow simultaneously it's the backbone, not a module. Full source code, API documentation, Docker deployment included. Before scoping the escrow flow on dispute, does the admin manually release or withhold funds, or do you need an automated resolution window with defined escalation rules? Regards, Haider

Hi I read your project and I understand you want a complete marketplace system with native iOS app in Swift, Android app in Kotlin, and a Node.js backend with MongoDB. The platform will include product listings, advanced search, real time chat between buyers and sellers, Stripe checkout, push notifications, and an admin panel to manage listings, users, and disputes. I have experience building marketplace and ecommerce style systems with secure APIs, JWT authentication, real time features, and payment integrations. I can build a clean and fast app experience that meets App Store and Google Play requirements and keeps the backend scalable and secure. One quick question before we start. Do you already have UI designs for the apps and admin panel, or should I create the interface as well? If the project is still open, send me a message and we can quickly discuss the architecture and milestones so we can start immediately. Best regards Hammad Hassan

Hello, I will build your marketplace with native iOS (Swift) and Android (Kotlin) apps, a Node.js REST API with MongoDB, JWT auth and role-based access, Stripe escrow payments, real-time WebSocket chat, push notifications via APNs and FCM, and a web admin panel for listings, users, and disputes. Full source code, API docs, and Docker deployment scripts included. For the 7-15 day timeline, I will prioritize by shipping auth, listings, and search first, then layer chat and payments in parallel since those modules have no dependency on each other. This keeps the critical path short. To scope the sprint plan accurately, I would need to know: how many product categories are you launching with, and do you have the UI designs ready or is that part of the build? Send me a message and we can go over the details. ~ Kamran

@nicolasalexandro

Hey — saw your post about a cross-platform buy-and-sell marketplace with native iOS and Node on the backend. Marketplaces like this usually get tricky around real-time listings, secure payments, and handling disputes smoothly. Quick question before I suggest an approach: Do you already have a preferred payment provider (Stripe, PayPal, etc.), or are you open to recommendations based on your target regions? I’ve worked on marketplace builds with native mobile frontends and Node backends, including listing management, chat, and secure transaction flows. If you share your current spec, wireframes, or any backend notes, I can review them and tell you what’s realistic for your first version and timeline.
